How to Replace an Audi Keys Replacement Cost G28 Engine Speed Sensor

286708_Volvo_Iron_Mark.jpg?Charles the Humble Technician shows how to replace the G28 Engine Speed Sensor. The sensor is located near the edges of the transmission just above the flywheel ring gear. It transmits a signal to the ECU via a grey wire (T55/49) which is then sent to the tachometer located in the instrument cluster.

1. Engine Speed Sensor

Located on the edge of the transmission above the flywheel ring gear G28 Engine Speed Sensor sends signals to ECU pin T55/49 using an uncolored wire. The ECU uses this information to regulate fuel and boost. It also sends a signal to the G5 Tachometer located in the instrument cluster.

The sensor is used as a reference point to connect with the G40 Camshaft Position Sensor. The ecu has to be aware of when the crankshaft has reached TDC and also the location of the camshaft so that it can activate the spark and injectors.

If this sensor fails the ECU will throw a P00160 code which means the Crank Shaft and Intake Camshaft aren't in sync, possibly indicating chain stretch or a jumped link on the upper timing chain. However, the error code won't appear on its own without additional information from other sensors (G4 and G40).

Testing is a bit challenging as there are two different connector pins and they have different functions however the best method to test it is by measuring resistance between the sensor and the ECU. If the sensor is operational, it should be reading about 1000 ohms. Look for signs of coolant or oil in the connector bay if you are experiencing issues with this part.

2. Injectors

Yesterday, while accelerating from the highway paytoll at a high speed I noticed a massive drop in power. It was as if the engine had run out of gas. Or my injectors weren't firing. This morning i pull out the spark plugs, 3 were drenched in gazoline, the fourth was dry. I put tissue over each injector hole, and when i start the engine with no sparks, the 3 with gazoline jump right out. The 4th one remains shut. I tested the ground connection on ECU pins 14/55, 30/55 and 48/55. i get 0ohm. Therefore, i think the issue is in another place.

I also tried to reset the PID without success. The car is able to start if the G28 is unplugged and runs fine when it is plugged in, but still has intermittent misfire issues at higher RPM. The coolant temperature sensor (G62) shows the wrong temperature of -49c even when i unplug it. Also, i noticed that the gauge for oil pressure in the cockpit shows 2 bar, whereas the actual pressure is 0.0 if i crank up the engine.

I'm not sure what to do. I believe that I've ruled everything else out. But i am afraid I might have missed something. If anyone has any suggestions, please chime in! TIA!

3. Fuel Pump

The fuel pump on the g28 is activated by a signal by the RPM sensor. The GM-style transmitter functions similarly to the G4 sender and both work on the 80,100,200, UrS, and audi replacement key service audi key replacement blade (https://Images.google.td/url?q=https://elearnportal.Science/wiki/Ten_Things_Your_Competitors_Help_You_Learn_About_Audi_Spare_Key) RS2 vehicles. You can easily find an extra in a wrecking shop or a parts store. It is simple to test them to do - just put your DMM in resistance mode and measure between pins 1 (with the bump on the connector's side up) and 2 (2nd from left on the black connector's side). They must be infinite Ohms.

4. ECU

Our 20vt turbo (3B AAN, ABY, and ADU) engines have an ECU that needs to know the speed and position of the crankshaft to make decisions about timing of the fuel injector, for example. To accomplish this, it utilizes a Crank Position Sensor (G4) and an Engine Speed Sensor (G28). If either of these sensors go bad you will get codes on the diagnostic scanner which can cause the engine to shut down.

Some of the symptoms of a failing G28 sensor include an inaccurate gearbox rev counter, gears shifting quicker than normal and/or misfiring when in gear. It is likely that the sensor is failing and requires to be replaced if you notice any of these symptoms. The good thing is that they are quite affordable and easily accessible, especially when you're looking at an Bosch model, which is what ours are. You can also choose the GM version of this component is also a good option.

5. Tachometer

A faulty engine speed sensor could be the cause of numerous issues in your vehicle. It's an essential component of the transmission in your audi advance key, as it transmits information to the ECU about how fast or slowly the car's engine is spinning. This sensor can cause the transmission to fail and other components of the car to be affected.

The G5 engine speed sensor is located on the edge of the transmission, above the flywheel ring gear and sends a signal directly to the ECU at pin T55/49 through an uncolored wire. The ECU uses this signal to control fuel and boost, as well as timig. It also transmits it to the G5 Tachometer inside the instrument cluster. You can check the sensor for any failure by checking the continuity between it and the tachometer, between ECU pin T55/49 and the instrument cluster connection on pin T6a/1 (trace [79]) and between T6a/1 and the instrument cluster pin T26a/12. It should show around 1000 ohms of resistance between those points. This part is common across the audi tt key fob 80-100-200-RS2 model, ranging beginning with the 1985 MC and up to the 1997 UrS AN and the 1995 RS2 Du You may also find them in wrecking yards.
